    @pvillard31 I fixed those tests. But I found the failures on other 
components. Is it ok?

> I'm trying to find a CassandraProcessor to fetch rows whose values in the 
> specified Maximum Value columns are larger than the previously-seen maximum 
> like QueryDatabaseTable.
> But I found only QueryCassandra. It just executes same CQL everytime without 
> keeping maximum value.
> and I think we also need convertToCsvStream option.
